Design of a Chainsaw Mill
Hynek, Jakub ; Vlašic, František (referee) ; Ranuša, Matúš (advisor)
The bachelor's thesis deals with the construction of a mobile log saw with an adjustable cutting height and attachment to a tree trunk. Part of the work is a search of known solutions for mobile log saws. The next part deals with conceptual designs and the choice of the most suitable solution. Furthermore, individual structural nodes are elaborated for the selected design and the function of individual parts is described. At the end of the work is the evaluation of the proposed structure.

Hodnocení harvestorové technologie
KOČÍ, David
The aim of this bachelor thesis is try to compare machines for felling trees at two private entrepreneurs with the same production focus but different machines. The main comparison lies in the performance, fuel consumption and financial costs of individual work operations in a pre-designated area. All this information will be converted to the annual work output of the machines.

Stanovení potřebného výkonu motoru v závislosti na úhlu řezu při řezání motorovou řetězovou pilou
KOUBA, Štěpán
This bachelor thesis deals with the measurement of the power of the electric chainsaw depending on the cutting angle. The engine power is influenced by number of factors which ultimately affect the work process and its economy. The main goal of this bachelor thesis was to make measurements which are needed to determine the cutting power of the electric chainsaw engine and to determine the factors which may affect this cutting power. The main factors include the power and the cubic capacity of the chainsaw engine, the type of clutch, the type and sharpness of used chain, the age of the chainsaw, the operator's experiences, the type and condition of the sawn wood and the angle of cutting angle.

The determination of needed power of chainsaw, depending on the type of sawn timber
LIEBL, Karel
This bachelor thesis deals with a power measurement of chainsaw engines. Their performance is determined by the type and condition of the sawn timber, version of the chainsaw, the chainsaw's power and also with the worker's experience. The main purpose of this bachelor thesis was to make all the necessary measurements required to determine the value of needed cutting power in connection with all the determining factors. Amongst the main factors are power and displacement of the chainsaw's engine, the worker's experience, embodiment of the clutch, the chainsaw's age and also the type and condition of sawn timber, as well as the used chain and the condition of its sharpening. Furthermore, I describe in my work what are the options considering the timber harvesting and during which operations are chainsaws mostly used.
